Abstract: The disclosure provides a wet-pressed tissue product comprising Agave fiber and having improved sheet bulk and good cross-machine tensile, toughness and durability properties.

Accordingly, in certain embodiments the present disclosure provides a three-layered single-ply wet-pressed tissue product comprising high-yield Agave fibers from the leaves of Agave tequilana, Eucalyptus Hardwood Kraft (EHWK) fibers and Northern bleached softwood kraft (NBSK), wherein the high-yield Agave fibers comprise at least about 5.0 percent by weight of the tissue product, the product having a CD tensile greater than about 450 g/3? and sheet bulk greater than about 7.0 cc/g.

Abstract: A system for treating cellulosic fibers to improve paper, board and tissue quality; the system involves splitting fibers into an original portion having original fibers and a refinable portion. The refinable portion may further be fractionated by one or more fibers properties by a fiber fractionation system into a first fraction and a second fraction. The refinable portion as a whole, or a fractionated fraction thereof, is then refined to produce refined fibers. Varying amounts of the original unrefined fibers, refined fibers and possibly additionally fractionated unrefined fibers are blended together to form an optimized slurry that is processed by a paper machine into an optimized paper product. A master control system, fiber measurement system and optional fractionation maintenance system are integrated with the overall system to regulate all processing.

Abstract: A method for manufacturing a layered paper or board web, in which method thick stock (M) delivered to the paper machine is diluted with tail water and the diluted stock (M1) is fractioned in order to produce two different stock fractions (A,B). The first stock fraction (A), with finer material, is conducted into the surface layer or layers of the web, and the second stock fraction (B), containing coarser material, is conducted into the middle layer or layers of the web. Before feeding into a headbox (15), the coarse stock fraction (B) is diluted with water whose consistency is substantially lower than the consistency of the water added into the thick stock (M) before fractionating. When water containing less solids than the normal tail water dilutes the coarse stock fraction, the stock fractions used for different web layers can better maintain their different properties, which improves the result of layering.

Abstract: A product and process of making an absorbent paper article such as paper products, towels, napkins and the like is disclosed. In the invention, one may supply a single furnish, or slurry, of cellulose fibers.
